Piers Morgan came out swinging against his former “Celebrity Apprentice” colleague Omarosa Manigault, saying that she offered him sex during their time on the reality series, then hurled a homophobic slur at him when he passed on her offer.

Morgan made his claims about Manigault, who recently made headlines due to her comments about the Trump administration during her stint on “Celebrity Big Brother,” in a Daily Mail column published Tuesday.

The British media personality held little back in his assessment of Omarosa, calling her “a vicious, duplicitous, lying, conniving, backstabbing piece of work.”

Morgan wrote that Manigault made her offer while they were taping the first season of “Celebrity Apprentice,” as they awaited details of their first challenge.

“Omarosa sidled up to me at the New York Mercantile Exchange and said, quite seriously, ‘Piers, do you want a showmance?’ ‘A what?’ I replied. ‘A showmance. You know, a romance on the show — we get it on together. Happens all the time on ‘Apprentice.’ Everyone has sex together. Then we can make lots of money out of it,'” Morgan wrote.

“I stared at her grasping, ferociously ambitious little eyes, and laughed,” Morgan continued. “‘You must be joking, you deluded woman.’ She didn’t take it well. ‘What are you? Gay?'”

Last week, Manigault — who came aboard “Celebrity Big Brother” shortly after her stint with the Trump administration — opened up about her former employer, saying that the country is “not going to be okay” with Trump in the White House.

Manigault told Ross Mathews that she felt a “call to duty” to serve in the administration when her former boss won the 2016 presidential election, but once he took office, things went south.

“I was haunted by tweets every single day. What is he gonna tweet next?” she told Mathews through tears. “I mean, I tried to be that [stabilizing] person, and then all of the people around him attacked me.”

Omarosa's 11 Biggest Feuds, From 'The Apprentice' to the Trump White House (Photos)

White House aide Omarosa Manigault-Newman exited the Trump administration in 2017, and some reports said she had to be "physically dragged and escorted" off the premises. It's hardly the first time the "Apprentice" alum has gotten into a high-profile disagreement since coming into the public eye over a decade ago.

During her first appearance on "The Apprentice" in 2004, Manigault-Newman frequently bragged about her experience working with then-Vice President Al Gore. However, it was later reported that she cycled through four positions in two years before finally being asked to leave altogether.

Manigault-Newman became one of the original reality TV villains with her instantly iconic performance on "The Apprentice's" debut season. She clashed with nearly every other cast member that season, but perhaps her most memorable moment came when she accused fellow contestant Ereka Vetrini of racism over the phrase "the pot calling the kettle black."

Not one to let her 15 minutes expire, Manigault-Newman spun her star-making turn on "The Apprentice" into lasting reality TV notoriety. When she appeared on the fifth season of VH1's "The Surreal Life," she found herself under the knife -- literally -- of Janice Dickinson. The mock-threat sent Manigault-Newman over the edge, leading her to call Dickinson "a crackhead" and threatening to hit her "in the mouth."

When Manigault-Newman returned to the Trump boardroom for "The Celebrity Apprentice" in 2008, she found a new enemy in the prickly British TV personality Piers Morgan. Their feud persists even until today, but it began when Morgan pinpointed her as the biggest liability among the women and refused to pronounce her name correctly.

Radio personality-turned-daytime TV star Wendy Williams hosted Manigault-Newman on her fledgling talk show in 2008 to promote her book, "The Bitch Switch." That interview quickly devolved into a series of snide comments about each other's looks and a full-blown argument about whether or not Manigault-Newman is a good representative for the black community.

Her third and final "Apprentice" appearance was in the show's "All-Stars" season in 2013, when she again clashed with Morgan, who was brought back to judge the contestants as a past winner. But it was La Toya Jackson who took the brunt of her anger when the singer dared to try and tell her what to do during one of the weekly challenges.

Manigault-Newman and "Real Housewives of New York" star Bethenny Frankel held animosity for each other for years, but the pair tried to turn their beef into ratings when the "Apprentice" alum appeared on Frankel's daytime talk show in 2013. Manigault-Newman slammed Frankel as "mediocre," saying she'd had an easier path to fame and success because of her race.

Michael Clarke Duncan's family hired a lawyer in 2013 to investigate the late actor's decision to rewrite his will to make Manigault-Newman, his then-fiancee, his main beneficiary a year before his death. The "Green Mile" star's sister also took issue with Manigault-Newman's decision to sell some of his belongings without their knowledge.

Shortly after taking on her position as a communications official in the Trump White House, Manigault-Newman made headlines for a verbal altercation with veteran reporter -- and former friend -- April Ryan. Witnesses said the two got into a heated argument outside the Oval Office, and Ryan later said Manigault-Newman claimed to have "dossiers" of damaging information about a number of reporters.

Manigault-Newman returned to her reality TV roots after leaving the Trump administration, entering the "Big Brother" house for the CBS competition show's first celebrity edition. One of her first acts as a born-again TV star was to tearfully warn that the country's "not going to be okay" with Trump in office. The White House fired back at a press briefing, boasting about how many times Manigault-Newman was fired on "The Apprentice."

While promoting her book "Unhinged" on NBC's "Meet the Press," Manigault-Newman played a recording of White House Chief of Staff John Kelly firing her. She also hinted at the existence of other recordings, including of Trump himself. The president has fired back, repeatedly calling his former aide a "lowlife."
